数学本身就是一门与生活联系比较紧密的学科,不同的是,学生所要学习的知识是人类几千年来积累的间接经验,它具有较高的抽象性,要使他们理解性地接受、消化,仅凭目前课堂上教师的口耳授受是不可能的。这就迫使教师改变教学观念,探索教学技巧,采取现代信息技术创设初中数学教学情境,从而提高教学的效果。 Mathematics itself is a subject closely related to life, the difference is that the knowledge that students want to learn is the indirect experience accumulated by mankind for thousands of years, it has a high degree of abstraction, so that they understandably accept, digest , It is impossible to accept and accept the teacher's speech in the present classroom only. This forces teachers to change teaching concepts, explore teaching skills, and use modern information technology to create junior high school mathematics teaching situations, so as to improve teaching effectiveness.
